Portable information apparatus having communications tools, a control system for controlling such portable information apparatus, and an apparatus having such control system
First Claim
1. A portable information apparatus having communications tools, said portable information apparatus including:
- a wireless transmission/reception section for transmitting to and receiving from an external wireless transmitter/receiver electromagnetic signals;
an operation section for performing various operations;
a display section for displaying status of the operations made by said operation section, and status and the results of transmission/reception operations made by said wireless transmission/reception section; and
a control section connected with said wireless transmission/reception section, operation section, and display section, for controlling overall actions of said portable information apparatus,said portable information apparatus further comprising reception means, within or outside said wireless transmission/reception section, for receiving a communication prohibition signal and/or a communication permission signal transmitted by the electromagnetic waves from an external facility, and for enabling/disenabling said transmission functions of said wireless transmission/reception section upon receipt of said communication prohibition signal and/or said communication permission signal,wherein said communication prohibition signal and/or said communication permission signal are/is weaker than the electromagnetic waves transmitted from said wireless transmission/reception section of said portable information apparatus.

Abstract
A portable information apparatus 20 having communications tools is provided with a switch 22a for instructing enablement/disenablement of transmission functions of the wireless transmission/reception section 21 of the portable information apparatus 20. The portable information apparatus 20, upon receipt of a transmission prohibition signal from an prohibition signal transmitter 31 installed in a public facility 30, determines whether the transmission functions must be disenabled and automatically controls enablement/disenablement of the transmission functions. The portable information apparatus is thus automatically turned off even when the carrier of the apparatus has forgotten to turn off the transmission functions, thereby allowing the carrier to perform necessary operations not involving transmission of electromagnetic waves without causing a nuisance to others.
